Here are the ingredients you’ll need to pick up:
Borax ($2.99 at Fred Meyer or Target in the laundry aisle)
Arm & Hammer Super Washing Soda (NOT Baking Soda–$2.99 at grocery store in laundry aisle)
Fels-Naptha Soap Bar ($1.56 at grocery store in laundry aisle)
5-gallon bucket with lid (ask the bakery at the grocery store you shop at if they have empty frosting buckets. I got mine at Albertsons for free)
10 gallon milk jugs (or other containers) that have been cleaned and rinsed out.
Optional: Essential Oil Drops for fragrance (I did not add this, I think it smells fine the way it is and I use white vinegar for scent removal if I need to)
1. Grate the entire bar of the Fels-Naptha soap. I used a food processor and it took about 10 seconds but who am I to judge? Lol
2. Put in a sauce pan with 4 cups of hot water. Stir continuously over medium-low heat until all of the soap has dissolved (10ish mins)
3. Fill a 5-gallon bucket half-full of hot water.
4. Pour in the soap mixture. Add 1 cup of Arm & Hammer Washing Soda and 1/2 cup Borax. Stir. I used a mixer attachment that goes on the end of my husbands drill. 🙂
5. Fill the rest of the 5-gallon bucket with water until it is full. Stir again.
6. Cover and let sit overnight.
When you open the top up the next day, it should have gelled and thickened slightly. Stir again.
8. Use a funnel to fill a clean laundry detergent container (or gallon milk jug) and fill it HALF way with the soap mixture. Fill the other half with water and shake.
When you’re ready to use the laundry soap, shake it in the container first. Then add: 5/8 cups for a regular top-loading machine -1/2 cup for a front-loading machine.
Side note: This does not make a lot of suds in the machine but I assure you, it still works great.
